Combines rotor evaluations

I ran the bison all season this year and with Dans help was able to get the rotor loss to a minimum and the best of of any rotor set up I have ever had. The only problem that I had was with what I think was overloading the chopper. This year in places our corn fell flat on the ground from heavy winds in early september. Sometimes I wonder if the bison feeds acrossed faster than the chopper can handle it. We were taking the whole plant of 200 bushel corn in and that is alot of material. Seems hard to complain about that yield but I wonder if the steep pitch setup is the way to go when running the bison. What do you think Dan or Tbran. I am going to be updating to a lower hour machine and not many have steep pitch setup in them. Also am sure your large gap door done the trick Dan.

Ok Guys were about to try Bison in lentils tomorrow! Tim or Dan! whats the diffrent peg configuration's on rotor for crop conditionsIJ if it's not separating well enough do we change pegs from right angles to helicals to a more in line with rotorIJ (point more straight to dischargeIJ) or more right angles to rotorIJ which way do pegs need to be to do more separatingIJ lentils will have some green weeds and slightly green vine! and just to make it interesting, I have dessicated some of the lentils! which will be tinder dry! lentils might go up to a ton_hectare! (10 to 15 bushels_acre) Rolf PS: About three weeks ago I didn't think we get any lentils and may be only seed back on our wheat! (Wheat might make the ton_hectare as well)

I'm getting ready for a more complete post to rotors but that might be a day or two. I'd like to go back threw some notes on comments guys have made. Many guys can't or won't post hear. As far as pins you might want to know this right away. Important thing is they are turned out to approx 1" from cage surface. Pointed straight at discharge bearing will retract the flow as much as I would ever want to. Heard of one guy that turned a bit past bearing toward cab. We set all our rotors up retracted toward engine 30 degrees from being pointed straight at bearing. I'd say 80% of the rotors stayed there and worked just great. We'd like to leave them there for all crops thus you read about longer slots in removable cage door. It is mainly corn where we found minimum loss while pointing pins straight at bearing. I believe we can retract a couple of the things we did to save nearly all the corn with some other tricks we have learned. Now if you move your pins from or between 30 to 90 degrees from bearing. 90 degrees will retract flow because pins will not work with helicals to move material over. My thinking is pins should be limited between 5 and 45 degrees from bearing. I have one real good hot rod that prefers the 45 degrees from bearing for it will pull material away from helicals. He has reported less than 1_10 of 1% loss in some of his 120 bu acre wheat, oats, and barley. This while having hard time burning over 10 gph. He had reported hauling in 1100bu per 22minutes to local elevator with just the one machine running. I guess I'm getting away from your more direct question. I hope you get the idea if you should feel you need to adjust pins diferently that what you have. Good luck

Thanks Dan Just what I need to know which way we might need to go with pins if we need to change them from your current recommendations, We currently have them set as you state of about right angles to helicals, and closest part of pins a fraction less than 1_2 inch from helicals. Rolf

Woo, Hoo Grain snorting, Deere sniffing, Grain fed Bison! She works guys First day I know, but very very smooth, in wire weed (hog weed) green lentil vine! if you baled the vine out of rotor and stacked it, you would have a big bale fire! Only low yielding lentils and not that much MOG, but the rotor loss was low on our first run, ROM convinced me to take out the helicals on the cage door and we have most likely, our lowest grain loss out the rotor in lentils we've ever had! Not grinding up no where near as much vine and I think we are getting lower grain splits ( With grub damage is very hard to not split the grain!) 190 rotor revs, two filler bars, steep pitched helicals over thresher, extended helicals in to discharge, Third helical over feeder inlet, cage cover over sep grate. running about 6 to 7 kms_Hr 9 meter flex 500, pulling 20 lbs boost most of the time with rises to 26 lbs boost in green patches. About 500 to 600 kgs_hectare crop yield Most amazing thing is How Smooooooth the thing runs! no slugs that jump boost engine to beeper or blowing thresher door in green patches! ( I Did blow thresher door twice! but I was pushing to 8 km_hr! Carn't cut it nice at that speed!) More testing to come, so far first impressions are good Rolf

what are your lintels, let me rephrase that, explain the crop lentils, again.

To add to tbrans question. What is grub damageIJ Is there a deduct for seed damage if not for seedIJ Simple test for damage after cylinder is slow down engine approx 25%, speed cylinder back up to your normal RPM, and carfully take a sample. We have found with viny edible beans that faster cylinder speed is better than too slow. I mean a RPM that don't split seeds and fast enough so material keeps flowing accross concave. Best of luck

lentils, a high protien pulse, "lens culinarus"; family; leguminosae; native to Africa and the Mediterranean. There are hundreds of varieties and landraces of lentils as it is probably the oldest and most widespread pulse crop used for both food and fodder. It is very widely adapted to a very large range of environments and climates. The seed is a small lens shaped seed between 3 and 8 mms in size and seed coat colour ranges between red, orange, grey, speckled to green depending on the variety. Seed pods contain two seeds per pod or only one seed when conditions get tough. Most lentils are consumed where they are produced. Although not the largest lentil producer, Canada is the world's largest exporter of Green lentils and now producing and exporting Red lentils as well. Since the mid 1990's, Australia has become a significant producer and exporter of Red lentils. The USA also produce small tonnages of lentils from the Pacific North West as well I think. Plants are a small bushy plant that are often naturally prostrate as lentils are generally hand harvested. Varieties have been selected and bred by the international ICRASAT and ICARDA pulse breeding centres for upright growth habit for machine harvesting. Some of these earlier varieties will substantially lodge when ripe. Plant height ranges from about 8" high during very dry years to about knee height in very good years. Its been a while since we have seen those nice high crops around here due to ongoing dry and drought over the last ten years. Yields in Australia range from the best at around 4 tonnes _ Ha to .75 or less tonnes _ Ha in dry years, Average is around the 2.5 tonnes _ Ha. Flex headers are an absolute must for lentil harvesting. Most grub damage is caused by the lucerne [Alfa Alfa to Americans! ] Seed Web Moth, "Etiella behrii" known as plain Etiella plus other unprintable descriptions to lentil growers. The moth is only a few mms long, lays it's eggs on the seed pod, hatches and burows into the pod and consumes or damages the seeds in the pod. Damaged seed then splits very easily when machine harvested. The merchants and consumers don't like the orange coloured seed halves in their sample although the red lentils are usually dehulled and split for human consumption. The green lentils are consumed whole. Your local supermarkets will generally stock lentils and lentil soup mixes as a lot of the alternative life style mob are into lentil and pulse based products. We don't object to this as they seem to be able to pay some bloody good prices for their lentils which we will gratefully accept! Go green, tbran! Eat lentils! Support those poor and destitute Australian and Canadian lentil growers!

Tim, can you clairify what you said about cdf giving 10% more than std. setupIJ Is this 10% more than pre 98 cyl or 10% more than modified 8 barIJ Our experience is 10% better than hyped 8 bar in beans, maybe a touch more in green stuff. not much difference in wheat except no vibration. still can't get real clean samples in either with cdf. thanks
